NITED STATES attain THEODORE FREY, OF GUIDE ROCK, NEBRASKA.

LIFTER.

Application filed April 18, 1922. Serial No. 554,701.

To all whom it may concern:

Be it known that I, THEODORE FRnY, a citizen of the United States,residing at Guide Rock, in the county of lVebster and State of Nebraska,have invented new and useful Improvements in Lifters, of which thefollowing is a specification.

My present invention has reference to improvements in pump or pipegripping and lifting devices and resides in the construction,combination and operative association of parts set forth in thefollowing description and falling within the scope of what is claimed.

In the drawing:

Figure 1 is a general view of the improvement.

Figure 2 is a sectional view on the line 22 of Figure 1.

Figure 3 is a sectional view on the line 33 of Figure 2.

Figure 4 is a perspective view of the grip ping element.

As disclosed by the drawing, I make use of a substantially U-shapedframe. One leg 1 of the frame F is of a greater length than the otherleg 2, the connecting element 3 between the legs being disposedangularly with respect to the legs. The legs have one of their facesserrated transversely as at 4 and provided with openings 5. Throughcertain of the aligning openings 5 there pass securing elements in thenature of bolts 6 which are engaged by nuts 8 that sustain on the framethe trough-like pipe or pump receiving member or clamp 10. The longerleg 1 has its outer end provided with a yoke-like portion 11 throughwhich passes the opera ing rod or lever 12. The connecting element 3 forthe frame is formed with a boss having an opening therethrough which maybe and preferably is enlarged from its outer end to receive therein asmaller boss 13 formed upon the inner face of a pipe or pump grippingelement 14, a pivot 15 connecting the element 14: to the fra e- Theelement 14 has its active face cam-shaped, concaved and toothedtransversely, as at 16. The gripping element 14 is thus in the nature ofa cam, and the operating rod 12 is pivoted thereto, as at 17. It will beapparent that the trough-like pipe or pump receiving member may beadjusted on the frame and that a pull on the arm will swing the concavedtoothed face of the cam into contact With the pipe or pump, so that thesame may be effectively gripped and lifted.

It is thought that the foregoing description, when taken in connectionwith the drawing will fully set forth the construction and advantages ofthe improvement to those skilled in the art to which this inventionrelates and that further detailed description will not be required.

Having described the invention, I claim 1. A U-shaped frame, atrough-like member adj ustably secured thereon a cam member pivotedthereto opposite the trough-like member, said cam member having arounded concaved toothed face disposed opposite the trough-like member,and an operating rod pivoted to the cam and guided through the frame.

2. In a device for the purpose set forth. a U-shaped frame whose armsare serrated and provided with openings, a trough-like memher having itsinner face toothed to engage the teeth of the frame, means passingthrough the trough-like member and the referred to openings in the framefor securing the said member on the frame, a cam member pivotallysecured to the connecting element of the frame and having a roundedactive'face which is concaved and toothed and which is disposed oppositethe trough-like member, one of the arms of the frame having yoke-shapedends, and an operating lever guided through the yoke and pivotallysecured to the cam.

In testimony whereof afiix my signa-
